3 Claims. (01. 17038) This invention relates to certain new and useand a substantially L-shaped part 2|. The parts in] improvements in wind motors. 2! of the braces are secured by bolts or in any The invention is concerned particularly with other suitable manner and as indicated generally the mounting of the wind wheels or propellers at 22 to blocks 23 arranged one above the other 5 whereby the latter may turn out of the wind,'at below the blocks I and rotatable also about the high winds, together with efficient means for recasing 'l as an axis. 1 turning the wind wheels or propellers into the From the above it will be apparent that when wind to the end that the device will not be easily the propellers H a r v lv p w is t ansdamaged during high wind storms d will opermitted to the shaft 8 and power from this shaft 10 ate to provide even power. may be used for driving any suitable mechanism. 10

swinging movement of the braces incidental to a movement of the wind wheels out of the wind and to a position with their axes at substantial right angles to the vane 23. Also, when the wind decreases the carriage 28 under a pull exerted by the weights 33 will move in a reverse direction or to the left (reference being had to Figure 3) whereupon through the connection between the carriage and the braces the arms I I and associated parts will be swung to the position shown in Figure 1 so that the wheels are again turned into the wind. Chain 30 is trained over pulley 38 mounted in bracket 25. When it is not desired to have the device operate the weights 33 may be removed whereupon the arms I: I and associated parts will swing back to a position substantially paralleling the vane 23.

Also, by adjusting the arms I3 relative to the arms I I slack in the belts I9 may be readily taken up.

Having thus described the invention, what is claimed as new is:

1 In a wind motor, a vertical casing, a driven shaft operating in said casing, a pair of arms connected at one end with the casing to rotate about the casing as an axis, supports, adjustably secured to said arm, horizontal bearings extending transversely of the supports at the outer ends thereof, shafts journaled in said bearings, wind wheels on one end of said shafts, belt and pulley drive means connecting the last named shafts with the first named shaft, and weight means connected with said arms for normally retaining the arms in reversely extending position; said weight means being responsive to wind pressure on the. wheels topermit said arms to pivot about said easing into a position substantially paralleling. one another.

2 In a, wind motor, a tower, a vertical casing, mounted on the tower, a Wind vane connected with said casing and fixed relative thereto, a vertical driven shaft operating in said casing, a pair of arms connected at one end with the casing one above the other and for rotation about the casing as an axis, supports adjustably secured to each of said arms, wind wheels on the outer ends of said supports and mounted to rotate on axes transverse to said supports, said vane including a fixed horizontal rail, a carriage mounted to move along said rail, means connecting said carriage with said arms for transmitting movement to said arms from the carriage and vice versa, and suspended weight means connected with the carriage for normally urging the latter in one direction, said weight means being provided with notches therein for slidable engagement with said casing.

3. In a wind motor, a tower, a vertical casing, rotatably mounted in the tower, a driven shaft in said casing, pulleys on the upper end of the driven shaft, longitudinally adjustable arms, means connecting said arms at one end with the casing for swinging movement about the casing as an axis, wind wheels mounted on the free ends of said arms, and including shaftsextending transversely of said arms, pulleys on said wind wheel shafts, belts connecting the first named pulleys with the second named pulleys, braces for said arms, means connecting said braces at one end with said casing for rotative movement about the easing as an axis, a wind vane extending from said casing and including, a fixed rail, a carriage moveable along said rail, weight means connected with the carriage for normally urging the same in a direction toward saidcasing, said weight means 3 being provided with. notches therein for the insertion of the casing, whereby said weight may slide longitudinally of said casing, and rods connecting said carriage with said brace members.
